Most sparsely populated state in the US. More pronghorn than humans. Yellowstone National Park. The Grand Tetons. Devil's Tower. Wildlife everywhere. Beautiful nature, and some of the last "untouched" wilderness in the lower 48. Lots of cowboys and Taco Johns. People from Wyoming are generally extremely friendly - as long as you fit their idea of an acceptable American. Strangers will wave to you on the road, but if you're not a white straight Christian gun-loving Republican who adheres to the proper gender roles, you will run into a lot of bigotry and ignorance. Wyoming is the self-proclaimed "equality state", but unfortunately, true equality is hard to come by (for the reasons stated above).

People in Europe: So you're American, are you from the East Coast or the West Coast?
Wyomingite: Um, Wyoming.
